FB-1771
In api_test.go, it was being used to make sure that incorrect input
produced the right errors; this is now handled by making sure the
error isn't nil and then checking its string against the expected
error string.
In executor_test.go and internal_client_test.go, it was being used
to compare QueryResponse structures, which contain an error.
handler.go now has a function specifically for comparing them,
which can provide additional detail if necessary.
Added a test for SameAs to handler_test.go.
This fixes the OriginalIP and RequestUserID in the main featurebase
package, and the Access and Refresh tokens, the UserInfo, and the
[]string of Indexes passed with context.Context(s) in the authn package.
An empty struct was used for all of these keys (and relevant helper
functions we added) to avoid allocations where possible while still
using the context functionality.
Some of the logic in the server.GetIndexes function was fixed.
The internal/ingest and internal/schema endpoints were developed with
intent that they'd be the primary interface new users would work with,
because they were Easy To Use, and did not require any kind of setup,
the counterpoint being that ingest done this way had performance issues
because it ended up with huge amounts of JSON parsing to reformat
things into our native format. But this was understood to be the price
of providing a new-user-friendly JSON ingest experience.
A year later, we have no evidence that it's ever been used. We never
even moved it out of the `/internal` path. It's a lot of very complex
fiddly code and we don't seem to be using it, and at this point, our
anticipation is that if we really need something, we'll use CSV, which
we already have working, or something in the new SQL code. Either way,
we don't seem to be using this.
enriched metadata for tables
added support for the concept of a table and field owners in metadata; mechanism to derive owner from http request metadata; metadata for table description
When doing tests, we create a ton of one-off clusters. This
turns out to be expensive and slow. Fixing it is surprisingly hard.
Fundamentally: If we're sharing clusters, we need to use different
indexes for each test, to avoid clashes. This changes index names.
As a side-effect, this reorders many partition-based things, like
the order keys are returned in. Thus, to fix this, we change a lot
of tests to no longer depend on the *order* in which strings are
returned.
Having done that, we can also discard the ModHasher behavior, since
that only existed to allow us to reliably predict partitioning.
The basic design is as follows: Instead of a cluster being a
[]*Command, a "shareable" cluster is now a []*Command plus some
flags, and a "cluster" is a pointer to a possibly-shared cluster,
plus a link to the specific test using this specific cluster,
and correspondingly, its test name suitably coerced to be a valid
index name prefix.
The "test.Cluster" object now has methods to allow retrieving an
index name, and also implemnts fmt.Formatter to let you use,
e.g., `%i` with it in Sprintf to get "the index name, plus an i".
(This works for everything but %p and %T.)
This allows us to consistently rework all the many things that
use index names in a persistent way.
We also have `MustUnshared` and `MustRunUnsharedCluster` methods
which allow us to specify that a given test needs its own cluster
for some reason. For instance, the tests that want to run backups
need their own isolated cluster, and the tests that want to close
or reopen nodes need their own cluster because a reopened cluster
won't have working GRPC for some reason.
On "closing" a shared cluster (actually the test-specific wrapper
that reflects a given sharing), we delete any indexes starting with
that test's index name prefix. Otherwise, the huge pile of open
indexes prevents `go test -race` from working on MacOS, where we
run out of address space too quickly.
This is fairly enormous but most of the individual changes are
fairly trivial things like replacing the string "i" with "c.Idx()".
We also tweaked a test that failed for me a couple of times to
not depend on sort order.
So, nShards used to be 10. If you run a complete test, with go
test -race, and you have the sample input for the unrelated
TestImportMutexSampleData configured to use 64K bit density and 2K
rows, everything is fine. If you run a partial test, everything is
fine. If you run a complete test with -race, but you skip
TestImportMutexSampleData, or reduce either the bit density or the
row count, you get a very strange panic where the go panic handler
panics trying to report what happened so we don't get a valid stack
dump. On Macs. This is as much as I could debug it after about 6
hours. Since there's no special reason to think we need all 10
shards, and 9 still tests the behavior, we're leaving this one a
mystery.
In the process of increasing the range for timestamp and subsequent
testing, I found and addressed a few bugs:
- min/max queries were not using timestamp specific comparators so
added that.
- Values from Import/ingest come to FB as relative values to epoch
whereas other BSI fields come as actual values and then
becomes relative to their respective bases within FB. so some
specific handling of that was added.
- However! Set queries use timestamp strings which are, of course,
the actual value they designate. So they have to become
relative.
- When bitdepth is 0, Min/maxUnsigned functions did not run
resulting in a count of 0 when there
was an actual value that was 0.
Also, this removes (now) dead code and updates/adds tests.
previously we allowed users to specify a granularity for timestamp
e.g. seconds, milli, micro, nano
however we converted everything to nano before we stored it.
This reduced the allowed range for all time units to what
was allowed by timestamp. For example, with second granularity
you can represent billions of years within the capacity of
int64 but with nano its somewhere b/w 100-200 years.
So now, for timeunits of seconds, milli, and micro the range
is year 0001 - 9999. These limits come from what Go
supports.
So this uses unit specific function to translate
timestamps to values and vice versa to increase
the time range.
This adds a shard-based import endpoint which takes bitmap data for
all field types and imports data for the whole shard transactionally.
It uses the BitmapRewriter interface to try to intelligently allow for
setting and clearing bits simultaneously without multiple writes which
is especially helpful when ingesting into int-like fields, but also
allows clear-and-then-set behavior for set fields.
we change this to use a simple modulus to ensure maximally even
assignment of partitions to nodes rather than the hash thing we were
doing previously which may have helped minimize data movement when
adding nodes, though I'm not even sure of that.
The logic was duplicated in a few places, so we've also condensed
that. For now, we're skipping tests which have baked in assumptions
about which node a partition will end up on as we expect them to fail
until they are updated.
This commit addresses a bug in https://molecula.atlassian.net/browse/SUP-200 where
the Authorization header was not being set correctly when the token was passed via
"userinfo" in the context and not "token".
Now, we prefix the token with "Bearer " when the token comes from userinfo.
This commit also adds a unit test for this function, and simplifies logic. It also
fixes a test that didn't quite test the behavior we wanted.
This test tries to verify that we can create multiple fields on a cluster
without deadlocking or getting errors *other than* ErrFieldExists or
wrappers of it. The "or wrappers of it" implies a change to ConflictError's
semantics, but honestly I think it should have had those semantics all along.
this is related to work for [fb-1127](https://molecula.atlassian.net/browse/FB-1127)
cardinality reporting has caused no shortage of issues such that we recommend
disabling them almost everywhere.
this commit removes the cardinality calculation for right now, as well as the option
to enable/disable schema details.

i used this script, a little clunky but it got the job done
```bash
for file in `find . -type f -print | grep '\.go'`; do
sed '1,/^\/\/ limitations under the License.$/d' $file > $file.tmp;
result=`cat $file.tmp`
if [[ result != "" ]]; then
gofmt $file.tmp &> /dev/null;
if [[ $? == 0 ]]; then
mv $file.tmp $file && gofmt -w $file;
else
rm $file.tmp;

Underlying goal: Don't use the http client to send messages back to the
local host. Also, when sending data to other nodes, don't collate it
from an ImportRequest into a completely different format, then immediately
collate that back into an ImportRequest. This does require changing
the logic over in ctl/import to make it create an ImportRequest.
Also, add additional testing to make sure we're actually trying anything
at all with several combinations (such as submitting import requests
which don't match the configuration of index or field), and improve
test coverage for that.
This introduces the ability to tell an http/client InternalClient about
a specific API that it should use for local queries where applicable.
That's not implemented outside of the import stuff, but should probably
be applied eventually to other things that are trying to talk to many
nodes one of which may be the local node. That behavior is contingent
on passing in a Qcx, because it is implicitly tied to an existing
execution context, and it can't assume that it can create a new one,
because that could deadlock.
The merge lists behavior was flawed in that it would drop one item
from the list per merge, which means that, with high replication
and low number of distinct items, it could even produce an empty
list.
The actual "is there anything wrong" logic is fine, but the list of
clashing values set for a given record is not.
Unfortunately this also doubles the time the test takes, to
21 seconds on MacOS. OW.
It's hard to do this remotely sanely for the fragments, but the
translation and collation process itself could be fairly slow on
large data sets, so we should check occasionally for canceled
context and return early if no one needs the result anyway.
Also, take out no-longer-correct comments from the test case.
We support query parameters for details (default false) which
request additional data, and for a limit (default 0/MaxInt32)
on number of results returned to limit the amount of spam
produced if there's a lot of results. The simpler default
output should reduce load and runtime significantly, and the
ability to specify limits makes it easier to get reasonably
small responses.
There's some context support here, but the underlying filters
don't take contexts or check for them, which is probably
a flaw but might be a bit large to correct for this.
Despite being large, this set of changes is actually
fairly well contained within the mutex-checking code.
This implements a fairly straightforward sanity-check for mutexes,
implemented as a bitmapfilter at the fragment level, and with higher
levels combining results. There's two endpoints, an internal endpoint
which only checks the local node's shards, and an external one which
forwards requests (using the internal endpoint) to all the other nodes.
The internal endpoint does not do key translation, the external one
does.
The transmission format is a probably-inefficient JSON blob, and
returns data separated per-shard so we don't have as much merging
work to do.
This introduces a horrifying monstrosity function which tries to
sneakily corrupt mutex fields and which has to be exported (EWWWWW)
but which is only present in _test code (!??!! THIS WORKS WHY).
Also one typo fix in unrelated code caused by not wanting to keep
fighting with gofmt about this.
This is a design to let us write test cases for ingest with schema setup
and data in the json formats we want to use, and results as alternating
queries and expected results, so we can just create new test files and
run the tests against them. We also have to report back what we created
when creating things.
In the process of developing this, I noticed that the documentation describes
ingest schema as allowing more than one schema operation, but we didn't support
this, and also it wouldn't do much good because there was no way to do partial
things like "just add a field". Fixed.
Also we implement comparison for ops, so the test output is actually
a test rather than just some data to visually eyeball.
In the process, realize that the handling of timestamps was wrong; we said that we
take them as raw numbers relative to the epoch, not as raw Unix timestamps.
Also a couple of related cleanups caught by doing the testing.
This partially-implemented prototype of the ingest API is based on our
programmatic ingest API reference. It has noticable limitations, most
crucially that it doesn't handle multi-node clusters right now. However,
it basically implements the expected semantics.
There's some noticeable performance issues to do with the high overhead
of sorting bits in order to import them efficiently, but this is fixable.
We also add the hooks to the internal client, and make the finisher logic
a bit smarter.
Much of this code was originally by Nia Weiss, but it's been merged
and restructured a bit to get things broken into logical commits.
In fact, we have a number of things assuming that values passed to Import
always fit within a single known shard, so, drop all the extra complexity
around this, drop the computation of fancy view/shard keys, and so on.
There's a lot of room left to improve this probably but it's at least
better, I think.
Unfortunately, there's a handful of things, basically all of which are
test cases, which were relying on this, so, we also add functionality
for splitting import requests by shards. But this allows us to stop
duplicating each shard's inputs one at a time... which turns out to
mean that we now care that the import operation can write back to the
import request. This only affects test cases, so we adopt a crufty
hack involving cloning import requests in those rare cases, and also
when reusing the same column IDs to write to the existence field that
we'd be using later to write to another field.
Note that even if we weren't overwriting the column IDs with positions,
we'd be sorting the column/row ID lists by row-then-column, which means
we'd still be corrupting the column ID lists. This may want to change
at some point.
We also reuse a single Tx for all the views, because DB-per-shard
means that should work fine, and reduces the cost of doing these
updates, probably.
Attributes are unmaintained and unused.
They have become more of a liability than a benefit.
This change eliminates them from the codebase.
The only user-visible change (assuming that attrs are not used) is that the attrs field will no longer appear in row JSON.
